Abstract: ABSTRACT     Crystalline layered mixed metal hydroxides (LMMHs) which are substantially free of unbound water and which conform esentially to the generic formula LimDdT(OH)(3+m+d), where m represents an amount of Li of from 0 to 3, D represents a divalent metal cation, and d represents an amount of D of from 0 to 8.0, T represents a trivalent metal cation, and (3+m+d) represents an amount which essentially satifies the valence requirements of Li, D and T, and where m+d does not equal zero, are prepared, in an organic reaction medium which is essentially free of unbound water, by mixing predetermined metal organo compounds in predetermined ratios and reacting the metal organo compounds with at least one reagent which supplies OH- ions to replace the beginning anions in the mixture of metal compounds.       A preferred LMMH is one which conforms essentially to the generic formula MgdAl(OH)(3+d), where d represents the amount of Mg per each unit of Al. Useful anhydrous gels are among the useful products.

Title: Improved method and products for treating asbestos
Inventor: MIRICK WILLIAM
IPC: B09B3/00
Filed: 1990-06-13
Abstract: A method for rendering harmless chrysotile asbestos comprises wetting the asbestos fibers with an aqueous solution containing about 1 to 25 % by weight of a weak organic acid, such as trifluoroacetic acid. Optionally, the aqueous solution further comprises about 1 to 10 % by weight of a source of fluoride ions, such as ammonium fluoride. The weak acid solution hydrolyzes the magnesium oxide units in asbestos while the fluoride ions attack the interleaved silica layers in the crystal structure of asbestos, thereby destroying the fibrous nature of the asbestos.

Abstract: An apparatus and method for acquiring biopsy specimens includes an outer cannula (20) having a bevelled distal end (22) and an opposing proximal end (28) having a Luer-type fitting (32). A stylet (34) having a like bevelled distal end (36) is inserted within the outer cannula (20) before the cannula is placed within the patient. Following placement of the outer cannula (20), the stylet (34) is removed, and a biopsy actuator (48) equipped with a biopsy needle (50) is then inserted within the proximal end of the cannula. The distal tip (52) of the biopsy needle is provided with a specimen retaining notch (56). The biopsy actuator (48) in-cludes a mating Luer-type fitting that is releasably attached to the proximal end of the cannula. The biopsy actuator (48) includes a spring-loaded trigger mechanism (68) for advancing the distal end of the biopsy needle (50) to expose the specimen retaining notch, and thereafter rapidly advances the distal end of the cannula to cut tissue prolapsed within the notch. The Luer fittings are then  disengaged, the biopsy actuator is withdrawn, and a second specimen may then be taken by inserting a second biopsy actua-tor in a like manner.

Inventor: HENRION JOEL
IPC: A61B19/00
Filed: 1990-10-05
Abstract: An interactive system for a local intervention inside a region of a non-homogeneous structure, such as the skull of a patient, which is related to the frame of reference (R2) of an operation table, and which is connected to a reference structure comprising a plurality of base points. The system creates on a screen a representation of the non-homogeneous structure and of the reference structure connected thereto, provides the coordinates of the images of the base points in the first frame of reference (R1), allows the marking of the coordinates of the base points in R2, and allows the carrying out of the local intervention with an active member such as a trephining tool, a needle, or a radioactive or chemical implant. The systems also optimizes the transfer of reference frames between R1 and R2, from the coordinates of the base points in R2 and the images in R1 by reducing down to a minimum the deviations between the coordinates of images in R1 and the base points in R1 after transfer. The system also establishes real time bi-directional coupling between: (1) an origin and a direction of intervention simulated on the screen, (2) the position of the active member.

Title: Dripping set with an automatic-closing-pad float
Inventor: HUNG YUNG-FENG
IPC: A61M5/168
Filed: 1992-04-29
Abstract: ABSTRACT        A  dripping set with an automatic-closing-pad  float, in which a fixed pad seat is furnished in the lower part  of a fluid reservoir; the fixed pad seat has a through hole;  a movable  pad float made of silicone is put above  the  fixed pad seat, and the pad float is able to float above the fixed pad  seat by means of a fluid so as to maintain the  through hole  in  open  condition, and to let a fluid  flow  into  a patient's  vein. As soon as the fluid is drained  away,  the pad  float    will fall downwards as a result of  having  no floating  force  to support the float to close  the  through hole  automatically, and then a given volume of  fluid  will remain  in the fluid hose to prevent the blood in vein  from flowing reversely, and to facilitate replacement of the drop bottle.

Title: Process for the preparation of cationic paint binders
Inventor: FEOLA ROLAND
IPC: C08G18/50
Filed: 1992-05-06
Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a process for the prep-aration of self-crosslinking cationic paint binders which can be diluted with water after protonation and are based on modified aminoalkylation products of phenols; to the binders prepared by this process and to their use for formulating water-dilutable paints, in particular electrodeposition paints which can be deposited cathodically.  The process is characterized in that an aminoalkylation product of a phenol containing at least one secondary amino group is reacted with epoxide compounds, and after temperature treatment, the reaction product is reacted with partly blocked isocyanate compounds.  The process permits the use of blocking agents which allow stoving temperatures in the range of 130 to 150°C.

Abstract: Abstract of the Disclosure An improved method for determining the approximate consumption rate of alcohol by a human subject includes the steps of using a blood sample from such subject to develop a subject serum panel.  Such serum panel includes at least twelve constituents, preferably more.  Two of the constituents are HDL and magnesium.  The subject blood serum panel is then statistically compared with a reference panel providing categories of rates of alcohol consumption such as light-to-moderate, moderate-to-heavy and very heavy.  The reference panel also includes HDL and magnesium as constituents.  That category of alcohol consumption which best characterizes such subject is then identified, thereby diagnosing the approximate alcohol consumption rate and, therefore, the presence or absence of probable alcohol abuse.  Selenium, copper and/or zinc may also be included as constituents.  Reference and subject panels may also be developed to include considerations of gender and ranges of age.
